Who is the Iron Patriot?

Most fans of Marvel know that Iron Man and Captain America weren't exactly on the best terms when Cap died. That's not to say that Iron Man necessarily wanted him killed for not agreeing with him. But maybe Tony Stark felt such remorse over the death that he's decided to rebrand himself as a hero? The above teaser image was released by Marvel and depicts the silhouette of what appears to be Iron Man with the Captain America star on his chest. The picture features the question "Who is the Iron Patriot?" Guess we'll have to wait and see.
